Paulette, I came across the 1850 OH census and found the following : 1850 OH Census for Belmont Co, Somerset Twp (BEsO409), conducted Aug 3, 1850, lists: ADAMs, Patrick, 57, M, Tavern Keeper, MA, along with Elizabeth, 55, F, MA, and the following children: John, 17, M, None, OH; Elizabeth, 16, F, OH; and Edward, 10, M, OH. Also, living with them was Abigail HARPER, 35, F, MA.
Abigail may be their daughter who married William HARPER. William supposedly died in 1841, but there is a big gap in age of children. Do you know if these are all Patrick's children?
I haven't had much luck tracking down Patrick or Levi DAVIS. Does this fit with you lines?
